WTA/ESSESL To all whom it may concern:

'FREDRICK w. EAGER, or win'r'nnor, MAssAoHusEr'rs, ASSIGNOR To UNITED snon MACHINERY coMrANY, or PATERSON, NEW JEnsEY, A CORPORATION or NEW JERSEY.

Be it known that I, FREDRIGK a citizen of the United States, residing at Winthrop, in the county of Suffolk and State of hiiassachusetts,have invented certain Improvements in Holddownsffor Last- ]ing-Machines, of which the following description, in connection with the accomfpa'nying drawings, is a specificatlon, like reference characters on'the drawings indicating like parts in the several figures.

This invention relates to lasting machines and particularlyto means for holding the work in bed lasting machines.

Inlasting shoes upon the commercial bed lasting machines,. it is necessary that'the shoe be held down firmly upon the toe rest "and it is important that the innersole be firmly held at and adjacent to the channel hp at the end of the toe and at the outer or more curved si'de of the toe because while the upper is being wiped over the edge of the last and over the feather of the inner sole the innersole/tends to crumple up at the channel or the rib line, or even to be displaced -bodily unless it is securely held against such action. The difficulty from crumpling of the innersole has seriously-increased within the past few years during which the great advance in the price of leather has obliged manufacturers, in order to keep as near as possible to the former manufacturing cost,

to use a thinner innersole or one which is of less firm quality, it having. been found that such an innersole will give good satisfaction provided the shoe is properly lasted and welted.

In addition to the difficulties arising from the crumpling up of the innersole at the channel and the consequent displacement of the lip which determines the stitching line by which the welt is attached around the toe, the use of these thinner and more flexible innersoles greatly increases, as would be expected, the liability that the lip or rib will be bent inwardly or overridden in lasting the toe of the shoe so that the upper materials lie upon it and render uncertain or impossible the proper stitching of the upper materials and welt to it. This difficulty is increased by the present use of bulky fabric toe stifi'ening material in place of the thinner but more expensive sole leather stiifeners. For these reasons it has become increasingly important to provide a sup- Specification of Iietters Patent.

found the swing that characterizes distinctively right and, left lasts. Furthermore, since the toes of modern, right and left lasts are not symmetrical with respect to the longitudinal median line, it becomes necessary in order that the lip of the innersole shall'be properly supported that the holding means be capable of adaptation to perform its function on either a right or left toe. j V V i The objectof this invention is to provide a simple and effective hold-down 7 device which will be well adapted to meet commercial conditions and which may be employed by the operator without loss of time in adjusting thesame, and which, furthermore, will result inincreased production and an improvement in the quality of the work turned out.

An important feature of the invention is the provision, in connection with a holddown finger for engaging the tip of the insole, of a supplementary member or auxiliary finger to bear in a similar manner upon the outer side of the toe, the said member preferably being capable of lateral adjustment without removal and also preferably without the loosening or tightening of its holding mechanism, as, for example, to fit innersoles of different patterns, or to fit either a right or leftcrooked innersole of the same pattern. Preferably the supplementary holding member comprises an arm pivoted to the finger but adapted to be swung to either side thereof into position to apply pressure to either margin of the innersole; that is, to apply pressure on the outer side of either a right" or a left innersole.

In the accompanying draWings,-Figure 1 is a perspective view of the improved hold-down together with the wipers and toe rest of a bed lasting machine; Fig. 2 is a plan view of the hold-down in a modified form in position upon the innersole of a shoe.

At A is shown the forward portion of a toe lasting head of the commercial type of bed lasting machine, such for example as that shown in United States Letters Patent to Brock, No. 1,018,466, granted February 27, 1912. At B is shown a toe rest which sustains the toe portion of a shoe during the lasting operation. The operating mechanism for the hold-down is substantially similar to that disclosed and fully described in printed British specification No. 19,512/11, to which reference may be had for details not herein given., The post 2 is mounted for vertical movement by means of a treadle, not shown. The head 6 is mounted for rotation on the post 2 and supports a carrier 8 mounted to slide therein transversely of the shoe and having friction means for holding it in any position of adjustment. The inner end of the support 8 carries a headed stud 9 upon which is detachably held a finger 10 provided with a transverse or supplementary pressing .member 16 which is preferably formed at its end with teeth facingtoward its free end. The member 16 is movably secured to the finger 1O andthis connection may be effected in any suitable manner, as by a. rivet 17 which will form a friction joint between the finger 10 and the member 16 and permit the same to be'adjusted at any desired angle to the finger,or to be swung to the side of the finger opposite to that shown in Fig. 2, for use on aright shoe. If desired, a slot 20 'may be provided in either the finger 10 or the member 16, or both, to permit adjustments of the finger and the member relatively to each other for large and small shoes. If desired, a nut or thumb nut 22 may be used in place of the rivet to provide a more ready adjustment of the finger 16 respectively to the finger 10. j 7

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A hold-down for lasting machines, comprising a member arranged to extend longitudinally of the shoe and to apply pressure to the toe end of the innersole, and a mem toe.

name to this specification in the 2. A hold-down'for lasting machines, comprising a carrier, a finger 10 secured to the carrier and extending lengthwise of the shoe at right angles to the carrier, and a supplemental fingerpivoted to the finger 10 for.

lateral adjustment to contact with the innersole alternatively at either lateral side of the finger 10.

3. A'hold-down for lasting machines, comprising a member arranged to extend lengthwise of the shoe and .to apply pressure to the toe end of the innersole at the inner side of the rib, and a member secured to said first member and arranged to be positioned to extend toward either lateral side of said first member into position to engage right and left innersoles adjacent to that portion of the rib which is on the outer side of the 4. A holddown for lasting machines, comprising, in combination, with ahold-down finger for engaging the tip of the toe of the innersole of a shoe,rof a supplementary member to'bear in a similarrmanner :upon the outer side of thetoe of the innersole, and a connection between said fingers permitting relative bodily adjustment of said fingersendwise to adapt them to fit different shapes of innersoles, substantially as de scribed. V

5. A hold-down for lasting machines, comprising a member arranged to extend lengthwise of the shoe and to apply pressure to the toe end of the innersole at the inner side of the rib, a second member connected therei to and arranged at an angle to said first member to bear in a similar manner upon the outer side of the toe of the innersole, said members being slotted, and a bolt engaging said slots and arranged 'tohold said members adjustably together.
